A method for accelerating a wake-up time of a system is disclosed. The method includes scrubbing and making available for allocation a minimum amount of memory, executing a boot-up operation of an operating system stored on the system, and scrubbing and making available for allocation an additional amount of memory in parallel with and subsequent to the boot-up operation of the operating system. The system may include one or more nodes, each of the nodes having a minimum node resource configuration associated therewith that corresponds to a minimum number of processors included in a node that are required to be activated in order to activate the node. The system may further include one or more partitions, where each partition encompasses at least one node. Each partition may be assigned a priority in relation to other partitions, and the partitions may be successively activated based on the assigned priorities.
